  • The touchscreen uses diffuse illumination in which a layer of material on the front of the screen is used to reflect infrared light.

    There are six optical motion-capture and motion-tracking cameras and 16 infrared illuminators - with a total of more than 1,000 infrared LEDs - located behind the screen.

    The cameras are unable to see through the diffuse layer, and when people touch the front of the screen, the infrared light reflected back shows the computer system where the screen is being touched.

  • The screen reacts to the input of users in no more than 50 milliseconds and also has a 120Hz stereo system to add to the experience.

    The technology used to create the touchscreen consists of off-the-shelf hardware and public domain software, including the Multi-Touch Vista user input management layer, Multitouch for Java, Community Core Vision machine-sensing technology and the Tuio protocol for multitouch devices.

  • The facility is being used by academics researching geographic information systems that capture, analyse and present data using techniques such as cartography, statistical analysis and database technology.
